Any copying, reproduction, performance or publication in any form outside the client organization without the express written consent of Navigant Consulting Inc. is prohibited. No Warranties or Representations Some of the assumptions used in the preparation of this wholesale electricity market price forecast, although considered reasonable at the time of preparation, inevitably will not materialize as forecasted as unanticipated events and circumstances occur subsequent to the date of the forecast. Accordingly, actual electricity market prices will vary from the electricity market price forecast and the variations may be material. There is no representation that our Ontario electricity market price forecast will be realized. Important factors that could cause actual electricity market prices to vary from the forecast are disclosed throughout the report. Notice of Confidentiality EXECUTIVE SUMMARY Navigant Consulting, Inc. (Navigant Consulting or NCI) was retained by the Ontario Energy Board (OEB or the Board) to provide an independent market price forecast for the Ontario wholesale electricity market. This wholesale electricity price forecast will be used, as one of a number of inputs, to set the price for eligible consumers under the Regulated Price Plan (RPP). Navigant Consulting used ProSym to develop our hourly Ontario electricity price (HOEP) forecast. Navigant Consulting’s Ontario ProSym database reflects the Ontario hourly load shape, all committed new entrant generation, best available information regarding the operating profile of Ontario’s hydroelectric generation (baseload and peaking resources), and operating characteristics and fuel prices for Ontario’s thermal generation. The sources of our assumptions are reviewed in detail in Chapter 3 of this report. The table below presents the results of our base case market price forecast produced by ProSym. The on-peak and off-peak prices presented are simple averages, i.e., not load weighted.

INTRODUCTION Navigant Consulting, Inc. (Navigant Consulting or NCI) was retained by the Ontario Energy Board (OEB or the Board) to provide an independent market price forecast for the Ontario wholesale electricity market. This wholesale electricity price forecast will be used, among other inputs, to set the price for eligible consumers under the Regulated Price Plan (RPP). This report presents the results of our forecast of the Hourly Ontario Energy Price (HOEP) for the period from May 1, 2008 through October 31, 2009 and describes the major economic and energy market assumptions and inputs for the forecast, as well the source of information. In addition, given that this forecast is based on a specific set of assumptions, the report also evaluates major risk factors in the forecast. This forecast of the HOEP will be used along with the following to establish the price for the RPP: o the regulated rate for Ontario Power Generation’s (OPG’s) prescribed assets, o the cost of non-utility generation (NUG) contracts administered by the Ontario Electricity Financial Corporation, o the cost of renewable energy supply (RES) and clean energy supply (CES) contracts administered by the Ontario Power Authority (OPA), o the cost of renewable energy standard offer program (RESOP) contracts administered by the Ontario Power Authority, and o the cost of the “Early Mover” and Bruce Power contracts administered by the OPA. In addition this forecast will be used to determine the estimated value of the OPG non- prescribed asset rebate (OPG Rebate or ONPA Rebate) as part of the RPP price. 1.1 Contents of This Report This report contains five chapters.
